A pandemic of political correctness gone seriously awry, due to the pussification of America.
A hyphenated American is anyone who takes up space on American soil who isn't white. Since one can no longer used terms like black, Negro, Chinaman, beaner, etc. we now have to say things like African-American, Mexican-American, Hispanic-American, Chinese-American, etc. ad-nauseam.
This phenomenon exists ironically despite the fact that all those people are still Americans, and only Americans! How can you be African and American? You can't. You're either African or American, not both. You can however be a black American (like a white American).
Of course, only non-whites can be hyphenated Americans, because white Americans are simply called Americans, no other term applies.
You can identify racist people if they say non-whites "take up space".
You can identify uneducated people if they use the term "pussification" over the age of 22.
Hyphenated Americans tend to have cultures slightly different from mainstream American culture; habits and traditions brought over from the countries their family emmigrated from. Many retain the drinks, food, language, customs,and music of their heritage. They also tend to look like their cultural background...Italian, Irish, Indian, Polish etc... Some Europeans feel that they are aping the culture of European countries, but often they are just acting as they were brought up to act by their European born parents. Whether Irish-American, Russian-American, Italian-American etc...they all share some cultural characteristics with the countries their families left.It really is not such a big deal, all countries with heavy immigration do the same, such as Canada, England, Australia and New Zealand. Americans get the most flack for it though.
